the big problem for investors is trying to finding the bottom everytime prices drop traders think the crash will not stop then he will lost the chance for buying cheap
my advice is never try to find an exact bottom ,this the reality of investement , in the best case investors will buy between 30 and 50 percent of bottom , for sure there some investors but little of them that have chance of buying in under 10 percent of loss because the final charts for all prices with bottom will come in the longterm the risk of bottom is lossing the chance always for buying and investing in the cheap prices
